Energy Company Obligation (ECO4) Scheme
The Energy Company Obligation (ECO4) Scheme is a UK government initiative aimed at improving the energy efficiency of low-income and vulnerable households. It requires major energy suppliers to fund upgrades, helping reduce energy bills and lower carbon emissions.
ECO4 follows a whole-house approach, meaning multiple energy-saving measures are installed rather than just one. Eligible homes can benefit from boiler replacements, first-time central heating, solar panels, insulation, and electric storage heaters, ensuring long-term energy efficiency and cost savings.

ECO4 Measures
To be eligible for this scheme, you need to own a property, be on qualifying benefits and have an off-gas network. Our experts help you navigate these parameters and determine your eligibility.
By embracing the ECO4 scheme, homeowners have the opportunity to install Air Source Heat Pumps, Solar Panels, and Insulation in their homes. These installations help you save on your energy bills and significantly reduce carbon footprints.
ECO4 is more than just an energy scheme. It’s an initiative that empowers homeowners to take control of their energy usage, fostering a more sustainable future. At Simple Green, we’re passionate about making green living accessible to all.
Take advantage of government-funded grants available for those on a low income. With the potential to cover up to 100% of the costs, this grant can make home insulation affordable. If you qualify for the ECO4 Funding Scheme, you could be eligible for a FREE energy efficiency measure.

What is the ECO4 Grant?
The ECO4 Grant is a government-backed scheme designed to help improve the energy efficiency of homes across England and Wales. It provides funding for energy-saving measures to eligible households, focusing on reducing carbon emissions and lowering energy bills.
At Simple Green Energy, we offer ECO4 grants with two types of funding:
- On-Gas Properties – Covers Boiler Installation and First-Time Central Heating Grants.
- Off-Gas Properties – Covers Solar Panel Installation and Electric Storage Heaters Grants.
Eligibility is based on factors such as income, benefits, or property type
What measures are included in ECO4?
The ECO4 Grant is designed to help households improve energy efficiency by funding specific home upgrades. It supports on-gas properties with boiler replacements and first-time central heating installations, ensuring better heating solutions. For off-gas properties, it includes solar panel installations and electric storage heaters, helping homeowners transition to more sustainable energy sources.
Eligibility depends on factors like income, benefits, and property type. Those interested in applying should review the criteria or seek guidance from an approved provider to understand their options.
How much does Boiler installation cost?
A boiler installation typically costs between £8,000 to £10,000, depending on the type of boiler, the size of the property, and the complexity of the installation. This cost includes not only the boiler itself but also labor, pipework, and any additional modifications required to ensure efficient heating and hot water supply. For many households, this can be a significant expense, making government-backed support essential for improving energy efficiency.
Under the ECO4 scheme, eligible households can receive a fully funded boiler installation at no cost. The grant is designed to help low-income and vulnerable households upgrade to more energy-efficient heating systems, reducing energy bills and carbon emissions. Funding is provided by the government, covering the entire cost for those who meet the criteria, which include factors such as income, benefits, and property type. If eligible, homeowners can benefit from a brand-new boiler installation without any out-of-pocket expenses.
What does the ECO4 Grant cover?
The ECO4 Grant covers a range of energy-saving measures to improve home efficiency and reduce energy costs. It includes boiler replacements and first-time central heating installations for on-gas properties, ensuring homes have effective and modern heating systems. For off-gas properties, the grant provides funding for solar panel installations and electric storage heaters, supporting a transition to more sustainable energy solutions.
In addition to heating upgrades, the grant may also cover insulation improvements, such as loft and cavity wall insulation, to help retain heat and lower energy consumption. Eligibility is based on factors like income, benefits, and property type, ensuring support is directed to households in need of energy efficiency improvements.
